WINDOW-CHAIR.

This invention relates to certain improvements in window chairs or supports, and more particularly to that type adaptedto be temporarily secured to a window casing or window sill to support a person washing the exterior of the window. a

One object of my invention is to so c011- struct the parts going to make up the chair that they may be readily folded to occupy the minimum space when not in use.

A further object is to so construct the device that the person seated upon the chair or support cannot readily look downward and thus cannot be affected by thealtitude at which he is seated.

Reference is to be had to the accompany-v ing drawings, forming a part of thisspecification, in which similar characters of reference indicate corresponding parts in allthe figures, and in which Figure 1 is a perspective view of a window chair constructed in accordance with my invention, a portion thereof being broken away; Fig. 2 is a vertical section substantially at right angles to the plane of the window; Fig. 3 is a top plan view of the frame of the chair in folded positionand with the side walls removed; Fig. 4 is an edge view of the chair in folded or collapsed form; Fig. 5 is a section through the hinge preferably employed for connecting one edge of the chair to the window sill; and Fig. 6 is a perspective view of one of the hinge members permanently secured to the window sill.

In my improved window chair, I provide a seat or bottom 10, of suitable width and of a length preferably substantially equal to dow. The bottom is preferably formed of bars, and these are reinforced and strengthened by two or more transverse cleats 11 extending across the under side adjacent to the ends. The ends of these cleats extend be- Speeification of Letters Patent.

yond the edge of the bottom and constitute the hinge members for detachably securing the seat to the window sill. The end of each cleat is provided with an upwardly-extending flange or terminal portion 12, and secured to the window sill and properly positioned to receive the end of the cleat is a socket 13. The socket is preferably formed of sheet metal bent into shape to form a base portion 14 adapted to be secured to the window sill, end portions 15 which prevent the lateral movement of the end of the cleat, and a top'or cover portion 16 curved upwardly and forwardly and having its free edge spaced from the base 1-1 a distance slightly greater than the thickness of the hinge member 11.

To secure the seat in position, it is held substantially vertically and the flanges 12 are caught beneath the free edges of the top or cover portion 16 and by swinging the upper edge of the seat outwardly and downwardly the parts come to the position indi cated in Figs. 2 and 5 and the seat is held against lateral or outward movement, and. the seat adjacent the window is also held against upward or downward movement. For supporting the outer edge of the bottom, suitable chains 17 may be secured adjacent the corners and may have their upper ends provided with hooks 18 adapted to be detachably secured to pins or rings 19 on the side of the window casing at a considerable distance above the window sill.

The side walls of the chair are supported upon two frames 20, which may extend up- ;wardly substantially parallel at the oppoisite sides of the bottom andbe locked in position, or which may be folded downwardly into engagement with the upper surface of the bottom. Each frame 20 is preferably formed of a rod bent to substantially U-shape and having opposite substantially parallel portions 21, 21 and a transverse connecting portion 22. The ends of the parallel portions 21, 21 are hinged to brackets 23 at the corners of the bottom, the connections being such that the free ends of the two frames may swing toward or from each other.

For limiting the outward movement of the frames and for locking them rigid in respect to each other, I provide a connecting rod 24: formed of two sections, each detachably and slidably connected to an intermediate coupling 25. The outer ends of this connecting rod are pivotally connected to sleeves 26 slidably mounted upon the outer side members 21 of the frames. By loosening the set screws in the coupling 25, the latter may be moved longitudinally and the rods may be separated. The two frames may then swing downwardly into engagement with the upper surface of the bottom. As an additional brace, a diagonal bar 27 may be pivotally connected to each collar or sleeve 26 and to the bottom along the outer edge of the latter. In folding the frame the collars 26 slide upward and the braces 27 swing over to a position adjacent the outer edge of the bottom.

The walls proper are formed of a sheet of fabric 28, supported from the two cross members 22 of the two frames and extending along the outer side of the connecting rod 24 and the outer corner members 21. The fabric walls are each of such height that the average person seated upon the chair cannot see over the edge, and thus his attention will not be called to the fact that he is sitting at a high elevation above the ground. The fabric walls do not prevent the end frames from folding toward each other, and it is therefore unnecessary to remove the fabric before folding or removing the chair.

The chair occupies but very little space when removed, as all of the parts fold into engagement with the bottom, and the operation of folding or unfolding the parts to inoperative or operative position, is so simple that no special skill is required.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A window chair having a bottom adapted to be secured to a window sill, frames secured to said bottom, each of said frames comprising a rod bent to substantially U-shape and having its ends pivotally secured to said bottom adjacent the ends of the latter, to permit the frame to assume an upright position or a position adjacent the surface of the bottom, collars slidably connected to upright portions of said frames, brace rods pivotally connected to said bottom and to said collars, a connecting rod formed of two relatively-movable sections secured to said collars for holding said frames in an upright position and a fabric wall extending from one frame to the other.

2. A window chair, comprising a bottom adapted to be secured to a window sill, frames secured to said bottom, collars slidably connected to upright portions of said frames, brackets pivotally connected to said collars and said bottom, means for holding said collars at predetermined distances apart when said frames are in upright position and means connecting the upper ends of said frames to prevent them from spreading apart.

3. A window chair, comprising a bottom adapted to be secured to a window sill, frames pivotally secured to said bottom adjacent the ends thereof, a connecting rod formed of two relatively movable sections connected to said frames above the outer edge of the bottom for holding the frames rigid in respect to each other when in their upright position and means connecting the upper ends of said frames to prevent them from spreading apart.

4. A window chair, comprising a bottom, hinge members secured thereto and having upturned ends and sockets secured to the window sill and each formed of sheet metal and including a base portion, upwardlybent end portions for engaging with the sides of said hinge members, and an upwardly and outwardly-curved or rolled portion for engaging with the upper surface of said upturned ends and permitting the longitudinal movement of the hinge members.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
